224 THYSANOPTERA AND ORTHOPTERA. 



This is a clumsy insect, leaping several inches to two or three feet 

 when disturbed. It hops about from one dead grass-stem to another, 

 and being of a brownish gray color, almost exactly that of the sand, 

 it was often difficult to detect because of its sluggishness. It rarely 

 seeks concealment. The males were often found in song, the method 

 of making music being the same as that described for Pseudopomata 

 hrachyptera. The rate of stridulation appears to vary with the 

 temperature, being more rapid at higher temperatures than at lower 

 ones. 



Chloealtis conspersa var. prima Morse. 



July 17. 



Coarse gravel near bushes in edge of woods. 

 Stenobothrus curtipennis (Harris). 



July 12 to July 30. 



Open woods; low underbrush; stubble fields; grass in moist or 

 dry places, even on sand dunes. 



The males were found in song during the latter half of the period 

 during which this species was captured. The method of making 

 music is the same as in the other species of this subfamily, and the 

 rate likewise appears to depend on the temperature, 

 gtenobothrus curtipennis longipennis Scudder. 



July 30. 



In timothy and blue-grass stubble. 



. Subfamily Oedipodinae. 



Arphia tenebrosa Scudder. 



July 21 to August 3. 



Grassy locations, either meadows or open woods, often on sandy 

 soil. 



The flight of this species is often accompanied by a rapid clacking 

 of the wings. When this occurs, the flight is irregular and butterfly- 

 like. Without clacking, flight is direct and well-controlled. A 

 flight of 13 yards without clacking occupied 3.2 seconds, while one 

 of 12 yards with clacking required 4.8 seconds. All the individuals 

 observed alighted on sand. 



Chortophaga viridifasciata (De Geer). 



July 1 to July 20. 



On grass and among low bushes on a moist beach. 

 Camnula pellucida (Scudder). 



July 4 to August 12. 



In grassy meadows or woods, along roads, or among small herbs; 

 moist or dry places; sandy or clayey soil; tall or short grass. 



This species was exceedingly abundant in grassy fields. Usually
